Product Overview
The JT Sprockets Steel Front Countershaft Drive Sprocket (Part #JTF824.12) is a premium, competition-grade drivetrain component manufactured by the world's leading aftermarket sprocket brand, JT Sprockets. This 12-tooth front engine sprocket is engineered to transfer maximum power directly from the transmission countershaft to your rear wheel hub via a standard 520-pitch drive chain. Designed as an exact OEM replacement alternative, selecting this ultra-durable 12T gear layout helps track, trail, and enduro riders modify their final drive gear ratio to maximize explosive low-end grunt, throttle snap, and heavy corner-exit acceleration.

Key Features & Benefits
-
SCM420 Chromoly Matrix: Forged from high-grade structural steel alloy that resists structural bending, chipping, and face pocket wear under extreme high-torque racing abuse.
[1]
- Precision Hobbed Profile: Every tooth face is fully hobbed, computer machined, and drilled rather than cheap surface-stamped. This achieves incredibly narrow assembly tolerances and fluid chain-roller engagement. [1]
- Heat-Treated & Bead-Blasted: Undergoes precise induction heat treatment to optimize surface rigidity while maintaining a low-carbon shock-absorbing internal core to withstand violent jumps and impacts. [1, 2]
- Zero-Play Internal Clearance: Machined to hyper-exact factory boundaries to eliminate countershaft micro-play, keeping power delivery linear and protecting output shaft engine seals from leaking. [1]
